dna probe meaning in English
dna探针
Examples
- Capacity evaluation of different media for isolating predominant phenol - degrading bacteria from activated sludge with community structure - specific dna probes
微生物群落结构探针杂交评价不同培养基从活性污泥分离优势菌群的能力 - The signal provided by the probe is a measure of the degree of hybridization . traditional dna probes are labeled with radioisotopes i . e . 32p , i25i , 3h or 35s
传统的dna分子杂交采用的是放射性标记的检测方法，这种方法虽然灵敏度高，但存在放射性物质对人体及环境的危害。 - Restriction enzymes and dna probes are used to determine the exact sequence , but it is possible to get a rough estimate by analyzing the frequency of recombination between the alleles of linked genes
虽然可以利用限制性内切酶和dna探针精确的分析出特定序列，但是在分析连锁基因等位基因间的重组序列时，会出现不准确的估计。 - The love wave device with the substrate of st - cut quartz and the guiding layer of si02 was used as the saw biosensor . dna sensor employing synthetic seb dna probe as a molecular recognizing component was utilized to detect seb by measuring seb dna in samples
该传感器采用以st一切割的石英晶片为基体，以510 :为波传导层的乐甫波( lovewaves )装置，利用具有分子识别功能的dna合成探针来实现对样品中sebdna的检测。 - Although this method gives high sensitivity , the radioactive labels present many problems such as a potential hazard to analyst and environment , which limited its application in dna diagnostic laboratories . in order to overcome these problems a serious of non - radioactive dna probes such as fluorescent , chemiluminescent and electrochemical probes have been developed . although these new methods display many advantages , they have not been used to take place completely the traditional method because of low sensitivity or complex equipment or other shortcomings
自20世纪80年代以来，各种非同位素如酶、荧光素、生物素、地高辛标记的化学发光法和荧光分析法以及以电活性物质做标记的电化学方法相继问世，这些方法虽然在一定程度上克服了同位素标记的缺陷，但由于存在灵敏度不够高或检测系统庞杂或仪器价格昂贵或标记物不稳定等缺陷，还不能完全取代传统方法。
